1 AC coupling ensures AVDD/2 bias.
2 Guaranteed by design. Sample tested to ensure compliance.
3 ICP is internally modified to maintain constant loop gain over the frequency range.
4 TA = 25°C; AVDD = DVDD = VVCO = 3.3 V; prescaler = 8/9; fREFIN = 100 MHz; fPFD = 25 MHz; fRF = 4.4 GHz.
5 Using 50 Ω resistors to VVCO, into a 50 Ω load. Power measured with auxiliary RF output disabled. The current consumption of the auxiliary output is the same as for the
main output.
6 The noise of the VCO is measured in open-loop conditions.
7 This figure can be used to calculate phase noise for any application. To calculate in-band phase noise performance as seen at the VCO output use the following formula: −213 +
10log(fPFD) + 20logN . The value given is the lowest noise mode.
8 fREFIN = 100 MHz; fPFD = 25 MHz; offset frequency = 10 kHz; VCO frequency = 4227 MHz, output divide by two enabled. RFOUT = 2113.5 MHz; N = 169; loop BW = 40 kHz,
ICP = 313 μA; low noise mode. The noise was measured with an EVAL-ADF4350EB1Z and the Agilent E5052A signal source analyzer.
9 fREFIN = 100 MHz; fPFD = 25 MHz; VCO frequency = 4400 MHz, RFOUT = 4400 MHz; N = 176; loop BW = 40 kHz, ICP = 313 μA; low noise mode. The noise was measured with
an EVAL-ADF4350EB1Z and the Agilent E5052A signal source analyzer.
